    SX1050 No Power

    Hi all, please forgive me if this is a topic widely discussed somewhere I can't find, but I've been doing a recap and restore of an SX1050 and all was good until I replaced the power transistors with the wrong thermal paste (it was conducive and messy). The fuse blew and I accidentally replaced...

    Yamaha RX-530 blowing fuses

    Hi everyone, I came across this forum, looking for some expertise on my broken RX-530, which I saved from my dad in order to fix it up. It's a childhood memory device for me, so I don't care too much if it's worth the effort in the end. To the problem: I found the device has its main fuse on...

    Onkyo Integra A-809 Blowing Fuses

    Hi all, I recently picked up this A-809 in unknown condition for $25. I figured for the price, it may be worth the troubleshooting project. I knew that it at least had the well known input selector issue, but it also appears to have a short somewhere. After opening I immediately saw that the...

    Pioneer SX-727 Blown Internal Fuse - what can I do?

    Hello AK, thanks for looking in. I'm having trouble identifying the cause for blowing an internal 3A fuse (# 2) in a Pioneer SX-727. I have reviewed other threads here and made some changes to my unit, but the fuse blew again while on the DBT, so I'm stuck, now. Can't measure voltages if it...

    Onkyo M-5030 keeps blowing

    I have an Onkyo M5030 that I recently acquired from a friend. I recapped it but when I went to turn it on it was at first stuck in protection mode and then the main fuses blew.

    Kenwood KR-720 blows 2A fuse when turned on

    Friend gave me this nice Kenwood receiver. Every time I turn the power on, the only 2A fuse on the circuit board blows instantly. (The other fuse is a 4A.) What is the likely culprit and is this worth trying to repair? Thank you DoubleA

    Scott 299B Blown Fuse

    Hello all! I love my Scott Amp, it sounds so good and was working perfectly for a year. A few months ago the fuse blew. It was a quick blo fuse so I tried another as I thought maybe it was a bad fuse, but same results. I let it chill for awhile. Now since I have time I thought I’d look into it...

    A little help with a H&K 730

    I have a 730 with a problem. One of the channels keeps blowing a fuse. Sometimes a new one will last a second, sometimes a week. I've taken it to a couple shops, and they will think they fixed it. They will test and everything, but within a week, it always blows the fuse again. Any ideas what...

    Where is fuse? Triode Corp trv 4se preamp

    my preamp started to light and then went blank. The manual says check fuse(s). But there is no obvious fuse. I follow the power source and see nothing except a yellow square on the power switch labeled DAIN. Is that the fuse? Any help appreciated.

    Celestion Ditton 662 Fuse Blowing

    Hi, I recently acquired a set of Celestion Ditton 662 speakers, since the reviews on them were quite good and so was their condition. I have them paired with a mostly overhauled Sansui AU-9500, and first impressions are good, but not as great as expected. Especially considering that the cheap...

    A friend of mine have an Akai AA-1020 with no left channel output. We found out that blown fuse could cause that and decided to order all of them since I'm already placing an order on Mouser.
